Under Armour® Partners with Texas Tech University to be the Official Outfitter of the University's Football Program

BALTIMORE, March 27, 2006 - Under Armour® (NASDAQ: UARM) today announced a five-year agreement with Texas Tech University to be the official outfitter of the university's Division 1-A football team. The Texas Tech Red Raiders will be outfitted in Under Armour's performance apparel and footwear, engineered to wick moisture away from the skin, enabling players to feel drier, lighter and more comfortable.

Under Armour now has "official outfitter" partnerships in The Atlantic Coast Conference, The Southeastern Conference, and The Big 12. The Company has outfitted the ACC's University of Maryland football program since 2004, and signed SEC powerhouse Auburn University this past December.

"Under Armour provides athletes with a performance advantage on the field," commented Kevin Plank, Chairman, Chief Executive Officer and President of Under Armour. "This partnership with Texas Tech is a great match for Under Armour and builds on our commitment to grow alliances with some of the leading football programs in the country."
